The main body 1a of the clamping tool 1 is a hollow rod-shaped body, and one surface along the longitudinal direction is a flat clamping surface 2. The surface of the clamping surface is covered with a cover material 3 made of a relatively flexible material such as synthetic resin. On the surface opposite to the clamping surface 2, rising portions 6, 6, whose ends 6a, 6a are bent inward, are formed at both edges as rails 5 for mounting to the jaws of the clamp. A C-shaped mounting groove 7 with a narrow opening is formed between the parts. On both end surfaces of the main body 1a, locking members 10, 10 are provided in which a locking portion 10a and a finger hook portion 10b are integrally molded into an L-shape when viewed from the side. This locking member 10 has a base 10c slidably inserted into a pin 11 provided perpendicularly to the end of the main body 1a, and a spring 12 loosely fitted into the lower part of the pin 11.
is biased in the upward direction in FIG. Therefore, the tip of the locking part 10a is normally in a state where the end of the groove 7 is closed, but by pushing down the finger hook 10b with your fingertip, the locking member 10 moves downward and the mounting groove is closed. The end of 7 is open. Although the main body 1a is formed to be long in the longitudinal direction (lateral direction in FIGS. 1 and 2), its length is arbitrary, and various lengths can be prepared as necessary. It is convenient to keep it.

In addition, 15 in the figure is a positioning tool, and the upper plate 1
6a and the lower plate 16b are connected by thin connecting parts 16c, 16.

The rail portion 32a of the rail member 32 is an elongated plate material with grooves 40 provided along the entire length on both sides of the central portion, and continuous sawtooth notches 41, . . . are provided on both upper and lower end surfaces. It is being A locking portion 42 for preventing the jaw member 35 from falling off is provided at the tip of the rail portion 32a. 44 in the figure is a catch that is slidably attached to the rail portion 32a,
This seat is made of a relatively soft material, and has a large number of anti-slip recesses 45 formed on both sides thereof. Note that the catch seat 44 is connected to the rail portion 32a.
removable from the catch plate 44, 4 in some cases.
This clamp 30 may be used with 4 removed. Further, the screw receiver 31 is provided with a tightening screw hole 47 at the lower end.

The male threaded rod 36 has a male thread 50a formed on its outer periphery to be screwed into the female thread of the threaded hole 47, a threaded member 50 having a spherical tip 51, and a wooden threaded member fixed to the rear end of the threaded member. It consists of a grip 52.

The jaw members 34 and 35 both have a horizontally long mounting portion 5 at the bottom that engages with the rail groove 7 of the clamping tool.
5, and is loosely fitted into the rail portion 32a of the rail member through mounting holes 56, 56 so that the respective mounting portions 55, 55 face each other.

One jaw member 34 has a recess 57 provided on the back surface of the mounting portion 55 so that the distal end 51 of the male threaded rod 36
is rotatably fitted into the recess 57 of the tip 51.
It is locked by a locking pin 58 so that it does not come off. Therefore, by rotating the grip 52 and moving the male threaded rod 36 forward and backward, the jaw member 34 moves along the rail portion 32a.

The other jaw member 35 has two claw plates 6 as ratchet claws in a hollow portion 60 that opens upward and downward.
A holder 62 holding 1 and 61 is fitted. The claw plate 61 has an opening 64 in the center through which the rail portion 32a is inserted, and protrusions 65 and 66 for attaching to the holder 62 are formed at the upper and lower parts. The opening 64 is a hole vertically longer than the cross-sectional shape of the rail portion 32a, and its upper wall portion 67 and lower wall portion 68 serve as the engaging portion of the ratchet pawl. Further, the holder 62 has an oblique body portion 7.
0 has an opening 71 vertically longer than the opening 64 of the claw plate, and a stepped ratchet release operation section 72 is formed on the upper side of the body, and a ratchet return operation section 73 is formed on the lower side. has been done. Torso 7
The front part of 0 is the holding position of the nail plate, and the two nail plates 61, 61 can be slid up and down with their respective protrusions 65, 66 inserted into the upper and lower guide holes 75, 76. Retained. This holder 62 is provided with a thin rod-shaped bending spring 77, so that the entire holder 62 is biased forward when attached to the jaw member 35.

FIG. 8a shows the occlusal state in which the holder 62 is held in the upper position, in which case the claw plates 61, 61 have a large inclination, and the occlusal parts 67, 68 of the claw plates are the continuous notches 41 of the rail part 32, Because the jaw member 35 is interlocked with..., the movement of the jaw member 35 is restricted. However, since the holder 62 is only held in the position shown in the figure by the elasticity of the spring 77, if the jaw member 35 is pushed to the left in the figure, the claw plates 61, 61 will move against the elasticity of the spring 77. oscillates, and the occlusal parts 67 and 68 and the notch 4
The occlusion with 1 is temporarily released. Therefore, it is possible to move the jaw member 35 to the left in the figure. That is, the ratchet mechanism R is constituted by the claw plates 61, 61, the holder 62, the continuous notches 41, etc., and when this ratchet mechanism is functioning, the distance between the jaw members 34, 35 narrows only. Jaw member 35 is movable.

FIG. 8b shows a non-occluded state in which the holder 62 is held in the lower position, and the release operation section 72 is operated to engage the stepped section 72a of the operation section with the upper wall surface 60a of the hollow section 60. As a result, the above-mentioned occlusal state is released. In this state, the claw plates 61, 61
Since the inclination of the jaw member 35 is slightly smaller than that in the occlusal state and is close to the upright state, the occlusal parts 67 and 68 of the nail plate no longer engage with the continuous notches 41, . . . of the rail part 32, and the jaw member 35 It becomes possible to move freely in both left and right directions along the . When the return operating portion 73 is pushed up from this state, the holder 62 returns to its original occlusal state due to the action of the bending spring 77.

These clamping tools 1 and dedicated clamps 30
When holding a long object using the gripper, fit the mounting part 55 of the jaw member into an appropriate position in the mounting groove 7 of the holding tool, and tighten the positioning tools 15, 15 on both sides of the mounting part 55 of the jaw member. By fixing the fitting position of the mounting portion 55, both jaw members 3 of the clamp can be fixed.
Attach the clamping tools 1 and 1 to 4 and 35, respectively. Note that when fitting the mounting portion 55 and the positioning tool 15 into the mounting groove 7, the locking member 10 is pushed down to open the end of the mounting groove 7.

For example, the operation method will be explained based on the case where two elongated plates 80 and 81 are butted against each other in an L shape as shown in FIG.
The width B of the held object (80, 81) is 4,35.
After setting the object to be held in the gap, move the jaw member 35 to the side where the gap becomes narrower, and pinch the object with the holding tools 1, 1 attached to both jaw members. engulf it. Jaw member 34,3
5, by keeping the holder 62 of the jaw member 35 in the lower position, the jaw member 35 can be moved smoothly and quickly.
Further, when moving the jaw member 35 to the side where the distance becomes narrower, if the holder 62 is placed in the above-mentioned upper position, the jaw member 35 will not move back and the object to be held can be reliably clamped. When tightening, place the holder 62 in the upper position, then tighten the male threaded rod 3.
Turn the grip 52 of 6 in a predetermined direction, and
4 is moved forward in the right direction in the figure, the object to be clamped is firmly clamped by the pair of clamping tools 1, 1 by the action of the screw.

This clamping tool 1 is long and has a horizontally long clamping surface 2, so it is suitable for clamping a long object. 35, the tightening points can be adjusted at will, and appropriate tightening can be achieved. Further, by tightening the pair of clamping tools with two or more sets of clamps, even more effective tightening can be achieved. Since the clamping abutment 1 is attached to the jaw members 34, 35 in advance, the operation is easy.

It should be noted that the clamping tool 1 and the clamp 30 can be prepared in various lengths, and the appropriate length can be selected and used depending on the size of the object to be clamped and the part to be clamped. good.

The jigs shown in FIGS. 13 and 14 are for attaching the clamping tool 1 to an ordinary clamp, and these jigs 85 and 86 have engaging portions 90 that engage with the jaw members of the clamp.
